Lake salam water treatment facility design for drinkable water needs in Universitas Indonesia depok campus

This research presented the design steps and calculation for each unit of the water treatment plant (WTP), due to its crucial role domestically and drinking purpose. It also illustrated and designed the procedures of the water processing units by estimating water demand and designing the unit process. The objectives of this work were to evaluate the water demand for a certain community and to present design steps and calculations for the required units of a WTP. The design of the WTP units was theoretically going to be applied to Lake Salam to be distributed as a drinking water in University of Indonesia Depok Campus. The quality and quantity of the Lake Salam water at various times were statistically analyzed and presented. The units of the treatment processes involved intake, coagulation, flocculation, sedimentation, adsorption, filtration, disinfection, storage, and pumping. The calculations and detailed drawings of the units were displayed, the average discharge and population used for the WTP design were calculated respectively. Besides, the calculation required some of the parameters to be estimated as field data, which were taken into assumptions. The design and amount of total investment of each unit of the WTP were tabulated. The research aimed to devise and evaluate the total investment required by designing and calculating the investment amount. During the calculation process, several parameters were estimated based on assumed field data. A number of factors such as the age of WTP, maintenance, economic analysis, design investment, and water demand had a great impact on the removal efficiency of the WTP units.
